Effect of pH on the Self-assembly structures of Block Copolymer Containing Poly(Acrylic Acid) as a Hydrophilic Block |
| 초록 |
A modular approach is an alternative method to the conventional sequential polymerization for the synthesis of complex block copolymers composed of diverse polymer blocks. We report the modular synthetic approach to synthesize poly(acrylic acid)-b-polystyrene having non-linear topology. Hydrophilic modules, discrete poly(t-butylacrylate) (PtBA) was synthesized by atomic transfer radical polymerization(ATRP), followed by chromatographic separation. The resulting discrete PtBAs were constructed to form a branched hydrophilic module, which was converted to the macro-chain transfer agents for RAFT polymerization of styrene. The resulting block copolymers were converted to branched-linear block copolymers that self-assembled into complex nanostructures in water. We describe the effect of pH of the medium on the morphology of the self-assembled structures of these block copolymers. |
